T RlCYCLE.

SPECIFICATION forming part of Letters Patent No. 477,140, dated June 14, 1892. Application filed September 21, 1391. Serial No. 406,370. (No model.)

.To all whom it may concern.-

Be it known that I, ARCHIE McDoUcALL, of Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented a new and Improved Tricycle, of which the following is a full, clear, and exact description.

My invention relates to improvements in tricycles; and the object of my invention is to produce a simple, practical, and durable machine, which is constructed in such a way that the driver may utilize both his hands and feet to propel it, and which consequently may be driven with great speed.

A further object of my invention is to provide a convenient and effective means of steering the machine.

To this end my invention consists in certain features of construction and combina tions of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure l is a sectional side elevation of the machine. Fig. 2 is a sectional plan of the same. Fig. 3 is a broken detail section on the line 3 3 in Fig. 2, and Fig. 4c is a detail view of the axle-ratchet.

The machine is provided with two main driving-wheels 10, which are placed side by side in the usual manner and which are mounted on a driving-axle 11, one wheel being made fast to the axle and the other being connected byacommon form of ratchet mechanism to facilitate the easy turning of the .machine, which ratchet mechanism consists of an inclosing case 12, secured to the wheelhub, a ratchet-wheel 13, secured to the axle and arranged within the case, and pawls 14, pivoted in the case and arranged to engage the ratchet wheel. The axle has mounted centrally thereon a frame 15, having depending end portions 16, which serve as hangers to support the shaft of the driving sprocket- Wheel 17, which sprocket-wheel is arranged directly beneath the driving-axle and connects by means of a chain 18 with the sprocket-wheel 19, which is secured to the axle. A reach-rod 20 extends forward from the frame and is supported on the steering-fork 21, in which the front wheel 22 is mounted in the usual way. The reaclrrod has a frame formed centrally thereon, and in the ends of this frame are mounted the shafts 24 of a frame 25, which frame is of a rectangular shape and is held to oscillate in the frame 23, as shown in Fig. 3, and this frame 25 formsa support for a lever 26, which has a socketed head 27 and extends downward and slightly rearward, being pivoted at its lower end, as shown at 28, to a connecting-rod 29, which extends rearward and has its rear end pivoted to the crank 30 of the driving sprocket-wheel 17. The outer ends of the shaft 24 terminate in depending parallel cranks 31, which are curved rearward and have pedals 32 at their lower ends. The socket 27 in the head of the lever 26 forms a support for the lower end of the handle-bar 33, which extends upward through the upper portion of the frame 25 and terminates at the top in a convenient handle 34:, the handle-bar being arranged so that it will be within easy reach of the tricycleseat. The handle-bar 33 carries near its lower end a sprocket-wheel 35, which is held to turn in the open middle portion of the frame 25 and which connects by a chain 36 with a sprocket-wheel 37, which is secured to the top of the steering-fork, and it will thus be seen that by twisting the handlebar the sprocketwheel will be twisted and the steering-fork turned so as to properly guide the machine. The handle-bar is intended to be moved backward and forward, too, in propelling the machine; but it will be understood that the sprocket-wheel 35 is arranged at the center of the motion, so that it will not have a reciprocating motion worth mentioning.

The machine is provided with a seat 38, which may be of any approved construction and which is mounted on the spring-tongue 39, the tongue being curved, so as to extend through a lug 40 on the frame 15, and it may be held in place by a cam-lever 41, adapted to turn so as to impinge on the tongue, or any other suitable mechanism maybe substituted for the lever. The seat, however, should be adjustable backward and forward, so as to bring the rider in the proper position in relation the handle-bar and the tlrivingpedals.

The operation of the machine is as follows: The rider places his feet on the pedals 32 and with his hands grasps the handle 34 of ICO the handle-bar, and then pushes back and forth alternately with his feet and hands, and this movement causes 'the frame to oscillate, and an oscillating movement is imparted to the lever 26, and the motion is transmitted by means of the connecting-rod 29 and crank 30 to the driving sprocket-wheel 17 and thence to the axle, the connecting-rod and crank serving also to convert the oscillating into a reciprocating motion. To steer the machine, the rider simply twists the handle-bar, which operates on the steering-fork in the manner already described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A tricycle comprising the usual driving and steeringwheels,a driving-axle connected in the driving-wheels, a frame mounted centrally on the axle and connected by a reach with the fork of the steering-wheel, a driving sprocket-Wheel mounted beneath the axle and having asprocket-wheel and chain connection therewitli,anoscillatinglever mounted on the reach, and an operative connection between the lever and driving sprocket-wheel, substantially as described.

2. A tricycle comprising parallel drivingwheels connected by a driving-axle, a steering-wheel arranged in advance of the main wheels and connected by a reach with a frame on the driving-axle, a sprocket-wheel pivoted on the axle-frame and connected by a chain with a sprocket-wheel on the axle, a seat mounted on the axle-frame, an oscillating and revoluble lever pivoted on the reach and con nected by a rod and crank with the driving sprocket wheel, and a sprocket wheel and chain connection between the oscillating lever and the steering-fork, substantially as described.

3. The combina.t-ion,with the tricycle Wheels and axle, the frame mounted on the axle, and the sprocket-wheel mechanism for driving the axle, of a reach extending from the axleframe .to the fork of the steering-wheel, a frame pivoted on the reach and provided with a depending lever, a rod-and-crank connection between thelever and the driving sprocket-Wheel, a pedal mechanism for oscillating the pivoted frame, a handle-bar mounted in" the pivoted frame and held to turn therein, and a sprocket-Wheel and chain connection between the handle-bar and the steering-fork, substantially as described.

4. The combination, with the driving-axle, the frame mounted thereon, and the sprocketwheel mechanism for driving the axle, of a reach extending from the axle-frame to the steering-fork, said reach having a horizontal frame formed centrally thereon, an oscillating frame pivoted in the reach-fra1ne and having a depending lever connected by a rod and crank with the driving sprocket-wheel, depending parallel cranks connected with the oscillating frame and carrying pedals at their lower ends, a handle-bar mounted in the oscillating frame and held to turn therein, and:

a sprocket-wheel and chain connection between the handle-bar and the steering-fork, substantially as described.
